The exact location of electrons in electron shells of atoms cannot be exactly ascertained. This is why VSPER atomic models represent the position of electrons (s, p, d, & f) using the probability of where they would most be expected to be found. 
Explanation:
This is because merely observing electrons changes their behavior. Remember that to observe something one has to shine light on it so it bounces back to the eye. Due to the negligible mass of electrons, mere photons of light will change their direction of movement, spin or other behaviors/properties.

Answer:
 F = ⅔ F₀
Explanation:
For this exercise we use Coulomb's law
          F = k q₁q₂ / r²
let's use the subscript "o" for the initial conditions
           F₀ = k q² / r²
now the charge changes q₁ = q₂ = 2q and the new distance is r = 3 r
        
we substitute
           F = k 4q² / 9 r²
           F = k q² r² 4/9
           F = ⅔ F₀
